....I would love your serious input here.

What causes a std YB conrod to break?Would 700bhp at a rev limit of 8000rpm just break it thru sheer power?.....As i noticed the arrow ones are rated to 10000rpm,does that mean i dont need em?...Plus how much stronger does shot peening give over a std unit?


I have had Marks advice and if i went his way it wouldnt be my own design
